HESI A2 Math Practice Test 2024

Correct Answer: A

Rationale: To calculate the total number of patients monitored, we add the number of patients each nurse monitored: 6 + 8 + 12 = 26 patients. Therefore, the correct answer is A (26 patients). Nurse 1 monitored 6 patients, Nurse 2 monitored 8 patients, and Nurse 3 monitored 12 patients, totaling 26 patients. Choices B, C, and D are incorrect because they do not accurately represent the sum of patients monitored by all three nurses.

Correct Answer: A

Rationale: To calculate the percentage of patients satisfied, divide the number of satisfied patients (120) by the total number of patients surveyed (150) and multiply by 100. So, (120/150) x 100 = 80%. Therefore, the correct answer is A (80%). Choice B (75%) is too low, Choice C (85%) is too high, and Choice D (90%) is also too high based on the given data. Thus, the correct percentage of patients satisfied is 80%.

Correct Answer: A

Rationale: Step-by-step rationale: 1. An even number is divisible by 2. 2. 12 is divisible by 2 (12 ÷ 2 = 6). 3. Therefore, 12 is an even number (Choice A). Summary: B: Incorrect - Odd numbers are not divisible by 2. C: Incorrect - Prime numbers have only 2 factors. D: Incorrect - Composite numbers have more than two factors.

Correct Answer: C

Rationale: The correct answer is C: 9:00 PM. To convert 2100 to standard time, subtract 12 hours from 2100 since military time is based on a 24-hour clock. 2100 - 1200 = 900, which translates to 9:00 PM. Choice A (12:00 PM) is incorrect as it would be noon, not evening. Choice B (2:00 AM) is incorrect as it represents the early morning. Choice D (2:00 PM) is incorrect as it is in the afternoon, not evening.

Correct Answer: A

Rationale: To solve for x, substitute x=11 into the expression x+(44/2x): 11 + (44/(2*11)) 11 + (44/22) 11 + 2 = 13 Therefore, the correct answer is D. Choice A: 2.5 is incorrect as the calculation results in 13, not 2.5. Choice B: 33 and C: 55 are also incorrect as they do not align with the correct calculation of 13.
